To (all whom, it may eoncern:

Be it known that LCLAREN ou ZANF. Davis, a citizen of the United States, and a resident of Buffalo, in the county of Erie and State of New York, have invented certain? new and useful Improvements in. Moisture-Supplyiiig A:Devices for Incubator-lieuters, of which the following is a speeiiication.

,(Ihis invention relates to devices tor supplyingl -moisture to the air by which incuhutors and like devices are heated or ventilated, and consists in the apparatus hereinafter described and claimed.

In the drawings Figure 1` is a vertical 4section of un incubator heater supplied With this invention and of the adjacent iortion of en incubator; is un enlarged vertioel section through 'the moisture device and through the 'plete ofthe heuter to which it is attached; Fig. 3 tine 3--3 of Fig. t;a'nd Fig. is a. perspective 'View 'of the moisture device l' In the drawing the .incubator casing 1 is supplied with the heater, which in this instance has a hot air inlet 2 and a hot air exhaust '3.354 The inlet and the exhaust connect directly with e vertical pipe or tube 4, and hns a top 5 provided with a central opening 6 that is adapted to be opened and closed by ,a demper '7 carried by t 1e usual thermostat rod 8. inside the pi )e 4 is en inner tube 9 ielosed et the top, an having a lateral tube "l0 connect opi-:mugs into the inner tube 9 und througi the outer tube f-t. Outside of the tube 4 is another tube ll, which does not extend downward as the other two tubes.

The inner or he top, and further 'tl'.ifgm. tube fr. .e the incuha.

The heatrediated from the tube 9 raises the temperutrue of the air in the spuce between the tubes und 9, which therevUpon, it' the domper? is dou-n or obstruetsthe @fee pussuge of t ie sir-out through the openin intgeiior of t 1.o ineutni or, und z'ntercireula-ting is a. cross section on they i), will ease through the inlet 2 into the,

through the same will escape from the inoubator by the pipe 3 and will rise through the tube fl and out'through the opening 6 whenever the damper 4.is sullieiently raised to permit this movement.

lt is desirable to suppl y moisture with the air entering au incubator, particularly for the purpose oi hatching ducks, and for this purpose the present invention was produced. A box or tank is provided adapted to hold and to supply water continuously to an absorbent material, and the absorbent material is'placed in the space between the tubes 4- and 9 so us to be heated and cause evaporation. of the water in said absorbent. Thus the evaporated Water is fed to the heated air in the hot air space o1' the heater, and the movement oi such air carries the moisture on through the inlet 2 into the interior of the incubator.

In the present form of the moisture device, the tank has its `front and back formed on concentric circles, and the connecting sides formed on radii of said circles. The 'iront plate 16 extends to the bottom 17 of the tank, and has in it near said bottom an opening 1S. The bottom 17 of the tank is continued outward in a trough 19 so that Water assing through the opening 1S will be hel( in the trough 19 and the water will be retained in the tankv 15 until the Water hss evaporatedor passed out of the trough 19 so far that a quantity of oir may poss into v"ne interior oli the tank through the openingr 18. This arrangement ermits a constant feed oi Water through tie opening 1S, but slowly' und"automatically, and enables a larve quantity of water to be lie ,t in the tord: 15 l'or feeding outward t ierefrom. The front plato 1G is bent on substantially the sonne curve its that of the pipe et.

Outside ot the 'front plate-16 is a plate 2() constituting the Aabsorbent support, and having one or more openings 21v (Fig. 2) et its bottoni within the trough 19. Various absorbente muy be used in connection with this device, but it' is found that fibrous material,

IOO

such us asbestos cloth, strawboard, and blot- :ting paper, or material` having some stiffness even when moist, is most convenient in use. A sheet 22 of such e material ispluced on the outer tace or the absorbent supporting plate 2() and is held thereon by inwardly turned vertical edges 23 of -said plate, which inwardly turned edges overlap the edges of the sheet of absorbent material 22. The plates 20 and 16 are by their curvature adapted to make suHicient frictional pressure upon the tube 4 to support the tank and its connected parts in proper position, althou h, if need be, the block 24, or other means o support, can be placed under the tank.

The operation ofthe device is as follows Havin moved the lamp 14 and depressed the she f 12, the moisture device is raised into place with a portion of the tube 4 between the plates 16 and 20, and thus the sheet of absorbent material 22 is in the hot air space between the tubes 4 and 9 with its inner surface exposed directly to the radiation fromv the heating tube 9, and still leaving the space between the tubes 4 and 9ree for the passage of air into said space, and thence into the incubator .passing the absorbent material 22. Vater from the tank 15 passes out through the openings 18 and 21 and comes in contact with the lower edge of the absorbent sheet 22. Itis sucked up into this sheet by capillary attraction, and'is evaporated from said sheet by the heat of the heating tube 9, and passes on into-theI incubator. The speed of evaporation can be increased and diminished by varying the size of the sheet 22. A very open material will take up andgive of water much more rapidly than will a closer and thicker fabric. The absorbent material must always extend to the bottom -o'f the trough 19, or s o far into the trough as to be in contact with the`water fed out from the tank 15. The adjustment of the amount of evaporation according to the time of year, and the particular circumstances under which the inheating t'he air to be delivered to an incubator, a water tank having a feed opening from its lower part, a sheet of absorbent material for absorbing the Water fed from said opening, and guides upon the side ,of said water.

tank for holding the side edges of saidA sheet. 2. -The combination of an incubator heater having walls enclosing a hot air sp acel for heating the air to be delivered to an incubator, a part of the outer wall of which space is a vertical partition, a water tank adapted to iit against the outer side of said partition, and having a lateral opening near its bottom, a trough adjacent to said opening and extending under said partition, a vertical plate eX.-

tending from said trough inside said partition7 and a sheet of absorbent material having one end in said trough and supported by said plate.
